Screen's gone blank and the green power button flashes intermittently

This monitor is about 3 years old and has worked fine for all this time, but last week, the screen started flashing on and off for couple of days and then went completely blank. Now any time I swith it on, the screen stays blank and the power button flashes (weakly) for about 5 seconds at 20 second intervals.

This is the way how to examine what's wrong with your LCD monitors. After you turned it on and the screen stopped working, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

Since you have tried another monitor with your computer, then we can only assume that your LCD monitor had gone bad.
If the light is green but you can't see anything on the screen, then most likely the backlight has gone bad. Unless you want to take the monitor apart, I would suggest buying a new monitor.

You more like have bad capacitors in the power supply. Open it up and look for capacitors with bulging tops. http://en.wikipedia.org/wiki/Capacitor_plague

Blank Screen & flashing button


It is one of three things, One is that it's not recieving a signal, mine flash when the computer is shut down, several monitors do this now. The second is that the either the video card is in need of service, or if you don't have a video card in your machine, it is either a connection that is intermittent, check the other end of the cable, or the monitor is in need of service, there is a circuit board that gives it a boost on start up. How old is the monitor and what brand? all the info is needed to go any further, thanks, if it is 5 years old more or less it is the monitor gone bad, more than likely

Please disconnect the Monitor Data cable from Computer.
If you see Dell Colored bars, it means, monitor is working fine,
If still black, please ask for replacement, since Monitors have 3 years of warranty if not purchased with the computer.

Now connect the cable back to computer and turn the computer off by holding the power button on computer and turn it back on...

Blinking Green shows that computer is in sleep mode......

Hope this should resolve the issue.

Green light blinking screen blank


Hi Suzee,

Is the green flashing on the tower or the monitor?

If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.

Check for the power supply light at the back of the tower.

Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.

Then connect the cables and check if it is working.

Monitor flashes image for split second then goes blank but green LED flashes as well


while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.

Occasionally this will not work for me, but if I repeat it it normally works

Hope this helps - my problem is intermitant so it may be different to what u guys have
